parts of camera







DSLR- A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that uses a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera. There are two main parts of the camera: The body and the Lens. Lenses draw The light into the camera and focuses it on the film plane. The shutter opens and closes to control the length of time light strikes the film. There are two types of shutters: a leaf shutter, located between or just behind the lens elements, and a focal plane shutter, located in front of the film plane.
There is the shutter release, the button that releases or "trips" the shutter mechanism.
Film Advance Lever or Knob is the thing that transports the film from one frame to the next on the roll of film.
Aperture dilates it and contracts to control the diameter of the hole that the light passes though, to let in more or less light. It is controlled by the f-stop ring.
And the viewfinder is the "window" through which you look to frame your picture.
Film Rewind KnobThis knob rewinds the film back into the film cassette.
 The casing of the camera which holds the encloses the camera pats is the camera body.
Flash Shoe is the point at which the flash or flash cube is mounted or attached.
The Self-Timer, a mechanism trips the shutter after a short delay - usually 7 to 10 seconds - allowing everyone to be in the photograph.
Shutter Speed Control controls the length of time the shutter remains open. Typical shutter speeds are measured in fractions of a second, such as: 1/30 1/60 1/125 1/250 1/500 and 1/1000 of a second.

Explanation for exposure: If the shot is exposed too long the photograph will be washed out.  If the shot is exposed too short the photograph will appear too dark.  Almost all cameras today have light meters which measure the light in the given shot and set an ideal exposure automatically.
